Which 2x 12v (30a) Power supply for dual xeon server

I have a dual xeon server board with a 350watt power supply, I can't add more than 4 HDDs to the computer without the power supply giving up, so I need to buy a new PSU.  I have a real hard time finding power supplys with the required dual 12v connector for my dual processors.  I need a very powerfull PSU (500watt+) can someone please give me a URL to a place where I can buy a great big power supply?

Thanks

Looking at the full intel m/b spec sheet appears you need a single 8 pin 12v connector rather than 2 x 4 pin 12v connectors, eg http://www.plinkusa.net/new-buyPS.htm or http://www.maxpoint.com/products/pow_supp/spec_pg/851ax/index.htm

I'm sure there are others and perhaps some already suggested are correct.

I looking for a PSU that has 2x 12v connectors.

I'm pretty sure your link, gjohnson99 has a dual 12v connector in that site somewhere, but I'm not really sure how to identify one.
http://www.antec.com/us/

NewBornVision, This URL points me to a PSU that says "dual 12v rails" whatever that is, but further down says (1x 12v connector (p4) ) I need 2
http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=1048976

I followed a few links from here to get to the specs for the PSU and still only 1x 12v connector
http://www.bjorn3d.com/read.php?cID=711&pageID=1091

I can't find any specs on this PSU, at least not the spec that says 2x 12v conector.
http://www.ncix.com/products/index.php?sku=12386&vpn=NEO%20POWER&manufacture=ANTEC


I've allready (stupidly) went to the retail PC store local to me and bought a 600watt PSU that ended up only having 1 12v connector.  So my home PC got a new PSU but my dual CPU xeon server didn't, it needs 2x 12v connectors on it.  I don't even know what a PSU like that is called, or if it even has a special name or I'd search for it (and I've allready searched, can't find any BIG PSU's /w 2x 12v's on it.).

Thanks for the help!

if you cant get the power supply, you can use the existing psu to power your system and a new psu (the one u brought now) to power up your drives...
make sure that you power up your drives first...

kiranghagCommented:
another care to be taken is to connect both psus to same power line

Problem_SolverCommented:
I agree with kiranghag my larger servers have 2+ PSUs, but in your situation having splashed out on a 600watt and since you probably only have space for one PSU then try a molex to P4 converter cable

http://www.xpcgear.com/psuaccessory.html

 for example. For stability would suggest connecting nothing else to the daisy chained connectors you use with the converter and using shortest length connector to PSU.

Thanks for the input!  I don't want to put anything jankey in the case (i.e. Anything requiring splitters or two PSUs.) because it's a production box for work.  I’m sure there is a PSU with 2x 12v connectors at 500+ watts.  I’m not too keen on using splitters because the PSU may not expect a 30 ampere load from the 12v connector and could break my system.  I really just need to know what one of these 2x 12v PSUs is called so I can search myself, or if someone has a link to a 2x 12v connector PSU that’d be great also.  I allready have a PSU like this running the system, but I need more wattage to power additional HDDs.  Thanks for the great ideas though, if it were my home box I’d do it in a heartbeat.

what is the server brand?
you may contact the vendor..

Coolhand2120Author Commented:
The server brand is Intel.  It has an Intel case, the motherboard is model number SE7501CW2.  Intel dosen't sell PSUs, I went to their web page anyhow and all it says about this motherboard is it requries a 30 ampere 12v current and 2x 12v connectors (one for each CPU).  Sorry I'm being so stubborn but I need the correct PSU for this box because it's for work, not play.  Thanks again for the help!

well, the motherboard could be from intel...but i doubt if the whole box is from it...
you must have brought this mahcine from a local vendor ar through some person.
get in touch with those people.

gotcha...
i had a look at the motherboard and its specifications..
seems like the two connectors are for **_r_e_d_u_n_d_a_n_c_y** and not "one for each CPU"

i tried to go through some links for your motherboard model and came up with these links quickly...you can try to call these people and directly enquire if these PSUs fit your needs. also let us know if it does..

ask for redundant power supplies...i think thats the word you need to look for.

YAY!  Dual xeon support!  That’s what I needed!  What to search for, and you've provided me with both that and URLs!

http://cache-www.intel.com/cd/00/00/07/70/77063_77063.pdf
    Neat PDF.  My case is made by Intel, it's the KDHBASE300, came with a crappy PSU too as it states in this PDF you found.  The 2x 12v connectors are not for redundancy, yes the other cases in the PDF have 2 PSUs for redundancy, I have the cheap Intel case (if there ever was such a thing) so it only has 1 PSU (slot).  
    The redundancy has nothing to do with the 2x 12v connectors though.  The motherboard actually has 2 connectors on the motherboard that are 12v connectors.  They are the exact same cable that you would use on a typical P4 board, but this board has 2 CPUs and it does require, just too turn on, both 12v connectors.  I just don't know what the name of the PSU that has the 2x 12v connectors is called.  And this PDF doesn’t even say.
   Maybe if I had 1 CPU I would only need 1 connector but I have 2.

Each of these links are to cases, I don't need a case. Just a PSU.  Actually the original PSU still works just fine, just too small.  And yes, I tried google before I posted here.

Thanks for all the hard work you guys put in on my question, I'd give everyone 1000 points if I had em!

"Looking at the full intel m/b spec sheet appears you need a single 8 pin 12v connector rather than 2 x 4 pin 12v connectors."

My motherboard has 2 completely seperate 4pin 12v connectors, maybe they call this a 8pin 12v connector, but I'm tellin ya!  They are two diffrent sockets!  Looks just like a P4 12v connector too!

Was looking at ftp://download.intel.com/support/motherboards/server/se7501cw2/tps.pdf pages 82 and 113.

Must be a different revision not listed by Intel.

How about that!  Now I must take a picture for you!  I'm reading off the side of the motherboard box for the model number, I gota get inside the machine (thats at work) so I can take a picture of the board for you.  I really hope I'm not mistaken here.

Don't worry about a photo, I quite believe that the mobo may have a different layout from the spec manual. I just didn't want you to think I was stupid!

Having looked at the 12v requirements I can quite see why splitting the P4 wouldn't be reliable enough or good enough quality, so if I found myself in your situation, then because there seem to be some good PSUs with the 8 pin, I would resort to an old method. (and this doesn't deserve points, cos its' too difficult for most people and you need a couple of dead P4 PSUs)

In days of old we had tools which could take the connectors apart (have been around for a long time just in different moldings) they work in principle the same way a credit card opens a yale lock. If you have patience and a fine sewing pin and a cork you could fashion a tool to take the connectors apart. By putting the sharp end of the needle in the cork you can insert the blunt end of the needle into the moulding alongside the spring clip which holds the wire in place, the wire can then be removed, if you been too forceful with the needle, you may need to carefully leaver the spring clip back out. Thus you could with the aid of some dead P4 psu's turn the 8 pin connector to 2 x 4 pin. Have to make sure you put the wires in the right way round during reassembly when wires can simply be pushed back in.

Anyway as I said not really a solution.

I have a whole room full of crimpers and connectors, irons, flux etc.  I just don't like to bust out the jerryrigging devices unless I have no other option.  I find the stuff I buy at the store (some of it) is higher quality than that I can muster in my workshop.  But from one propeller head to another RIG ON BROTHER!

yes...the links were of cases...idea behind giving links to case was
1. psu is included in case
2. price of psu+case and psu alone should be almost same
3. at some pages, they supported your motherboard
so if it has higher ratings and supports your motherboard, it should be the one you were looking for.

neways...i m not clear about what was the exact solution that worked for u...
